The Preparation of High-performance Mesoporous Proposed Pseudo-boehmite (γ-AlOOH) Modified by H2O2 Based on Molecular Dynamics

To efficiently address the current high cost associated with preparing pseudo-boehmite from organic aluminum, a low-cost alternative, AlCl 3 , is employed as the raw material. The sol-gel method is utilized, and H 2 O 2 is incorporated for the modification of pseudo-boehmite. The modification mechanism is thoroughly investigated through the use of X-ray powder diffractometer, scanning electron microscope, and BET data analysis, as well as molecular dynamics simulations. Under specific conditions (temperature at 80 °C, pH=7, and H 2 O 2 volume ratios of 0.5:1, 1:1, and 2:1), mesoporous pseudo-boehmite is synthesized with a specific surface area of 227 m 2 /g, a pore volume of 0.281 cm 3 /g, a pore size of 6.78 nm, and a peptizing index of 99.47%. A novel and innovative methodology for the cost-effective production of high-performance alumina is offered through the approach.
